High-precision shape measurement via DCOM interface

The flexibility of NetGAGE3D
sensors with regard to the composition of surfaces offers a
diverse range of applications.
All kinds of materials in various states of processing and even translucent
objects can be measured with an accuracy of a few microns or even nanometers
without contacting.
The NetGAGE3D family of sensors enables a wide variety
of applications
because of its various modifications and universal construction:

The data acquisition and processing software SoftWLI3D
can be thoroughly controlled via its integrated DCOM interface by
other programs.

Measurement
Principle: White Light Interferometer

NetGAGE3D is a compact measuring head based on the white
light interferometry measurement principle. It compares the path
length of the light reflected or scattered by the object surface
with a reference path length. In this patented measurement process,
the measuring head scans the object while moving in the z-direction.

The results is a 'depth image' of the object with a very low measurement
uncertainty. It combines the advantages of common tactile sensors
with the benefits of optical sensors: high measurement accuracy
and non-contact, high-speed scanning with a high data rate.

Measurement Examples

Shadowing is avoided through coaxial illumination.
Low lying surfaces in drill holes can be measured without any
difficulty.
The illustration shows an example of the measurement of various
tapered surfaces in a borehole approximately 10 mm deep.
By a similar method, tapered surfaces are measured in a 40 mm
deep borehole with a diameter of 3 mm.
